“It’s very important that we understand the status of those species, the challenges they face and the solutions for their conservation,” said Amy Fraenkel, the convention’s executive secretary, during a news briefing. While some fish species are targeted intentionally for harvesting, others may be swept up as bycatch or otherwise affected by industrial-scale fishing operations.
